Default Re: DUDE! Where's my locking freewheel ??!!

Thanks Ron!

It's real, but not commercially available anymore, unfortunately. It was a product made back in the '70s to allow fixedwheel riders to coast downhill. There is a mechanism activated by a lever and cable to enable lock/unlock on-the-fly.

I've been giving the idea some thought because it's also something that's needed for electric drives - in order to be able to have both freewheeling and regen. braking.

A web-search on "locking freewheel" led me here : )

I think I would design the changeover mechanism differently but the locking freewheel aspect seems sound.
